Hello everyone! Does anyone here have any experience converting a tourist visa into a Non-b in Chiang Mai? Do you need to hand in your passport with the other documentation for those 21 days or can you take it there afterwards to get the visa stamp?
TLDR : Answer Summary
To convert a tourist visa to a Non-Immigrant B visa in Chiang Mai, you need to submit your passport along with other required documents. Although normally you may get your passport back shortly (within 1-2 days), Chiang Mai requires you to have at least 21 days left on your current visa for the application process, which takes about 14 days. It's important to have a job offer and necessary documentation from your employer. The fee for a 90-day Non-Immigrant B visa issued in-country is typically 2000 baht.
